Abstract: A normal force applicator (11) for apparatus for bottom feeding articles from a stack. The normal force application (11) forms a rolling nip (28) between a roller (27) and a feed belt (5) designed to apply force to only a few of the bottom articles in the stack to be fed at a time. The rolling nip (28) ensures a constant normal force between the articles and the feed belt (5) that feeds articles to a separator (16) even using a very low applied force, independent of stack size. Also, since the roller (27) contacts only a few of the bottom articles, additional articles can be added to the stack readily even while the feeder is operating.

Abstract: An air supply system for the catalyst regeneration zone (10) of a fluidized catalytic cracking unit (41,10) also supplies a pressurized air stream to the turbine (27) of an electrical generating plant (27, 28). The compressor (17) which produces the pressurized air stream may be driven by passing the flue gas to the regeneration zone (10) through a power recovery expander (15). Preferably, the pressurized air stream is first heated by the turbine effluent in a heat exchanger (24) and then admixed with hot gas from separate turbine-type gas generators (32, 33) prior to being passed into the turbine (27). This provides a very practical and relatively low-cost cogeneration process.

Abstract: The invention relates to a fast charge circuit suitable for use with battery cells which can be charged at a 4C rate. Line voltage is transformed, full wave rectified and applied to the battery pack. A pair of voltage comparators monitor a sensing voltage which is indicative of the charging voltage-and the trough voltage of the battery cells. During a «window» when the sensing voltage is less than a predetermined threshold and trough voltage exceeds this threshold, the comparators indicate that charging should be terminated. Alternatively, if excessive temperature on the cells is detected or a selected amount of time passes without reaching full charge, fast charging is also terminated. After the fast charging interval trickle charging of the cells is employed to bring the battery pack to full charge- and maintain it there.

Abstract: A process for the production of 2,6-di-tert-butyl-a-methoxy-p-cresol and high molecular weight hindered phenols produced therefrom. A process is disclosed for the production of the methyl ether of 2,6-di-tert-butyl-p-cresol in such a manner that allows subsequent production of 1,3,5,- trimethyl-2,4,6-tris (3,5,- di-tert-butyl-4-hydroxybenzyl) benzene in the same pot. The process permits substitution of the methanol solvent/reactant with a hydrocarbon or halogenated hydrocarbon solvent to produce the high molecular weight hindered phenol. This aspect of the invention reduces production cost by eliminating expensive centrifugation associated with prior art processes. The process also conserves catalyst by recycling it in the excess methanol. The catalyst is a Mannich base such as 2,6-di-tert-butyl-a-dimethylamino-p-cresol formed from the reactants 2,6-di-tert-butylphenol and formaldehyde with dimethylamine. The invention is an important improvement over prior art processes in that the production of bisphenol coproducts, notably 4,4'-methylenebis(2,6-di-tert-butylphenol) is low.

Abstract: Method and apparatus for determining the saturation temperature of a solution. In an optical measurement vessel, the temperature of a sample of the solution is gradually decreased until crystals are formed and subsequently gradually increased until the crystals dissolve. The temperature is measured continuously and the formation and dissolving of the crystals is detected optically by means of a beam of polarised light which is transmitted through the measuring vessel, and passed through an analyzer the direction of polarisation of which is normal to that of the beam of light, and detected by a photodetector behind the analysator. Only when a small amount of optically active crystals is present in the solution, in which the direction of polarisation of the light is rotated, the photodetector measures a certain light intensity. The moment the last crystals, upon heating, dissolve is detected by the drop of the measured light intensity to a minimum value. The temperature of the solution at that moment is the saturation temperature of the solution. 
     Preferably the beam of polarized light is generated by means of a laser. For monitoring the transmitted beam, a beam splitter is preferably mounted in front of the analyzer, which casts part of the transmitted light onto a second photodetector.
